FLOW-INDUCED ORIENTATIONAL CHANGE OF AQUEOUS SOLUTION OF POLYMER AFTER AN ABRUPT EXPANSION IN PLANAR CHANNEL FLOWS

Flow-induced orientational change of aqueous solution of polymer after an abrupt expansion in planar channel flows

Flow-induced orientational changes of an aqueous polymer solution in planer channels have been studied utilizing optical rheometric technics.Two kinds of 1:4 abrupt expansion channels with the same width and different heights of 1 Day Moisturiser mm and 0.2 mm were tested in the experiments.0.5 wt% xanthan gum solution was examined as the test flui

Prospective randomized controlled study on small-window craniotomy versus ordinary large-window craniotomy in the evacuation of epidural hematoma

There is still controversy on the clinical efficacy of small-window craniotomy (SWCT) for acute epidural hematoma with concurrent early-phase cerebral herniation.This study compared multiple surgical and prognostic parameters of SWCT versus ordinary large-window Snoring Support craniotomy (LWCT), which aimed at providing evidences for surgical deci
